Products getting duplicated and not syncing correctly

Hi there, I’m trying to import my shopify products into woocommerce but they are getting duplicated:
1- I import them on the main plugin page (settings)
2- When I make any change in a Shopify product it is getting duplicated and the shopify sync button returns error

And also I want to know if I can import the shopify product id to a meta key on wordpress.

Thank you!
